+Thr fix to Path.GetDirectoryName almost fixed DirectoryInfo.
+
+However, the 3 lines of code you provided, cause a
+NullReferenceException under MS (instead of /tmp I use \WINNT) because
+the parent of the root directory is null.
+
+I've fixed this and also made our implementation work as MS does wrt
+nulls. Also DirectoryInfo.ToString () has been changed to match MS.
